BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to collapsible containers and more particularly to a collapsible box with improved characteristics.

2. Description of Related Art

Containers or boxes are widely used in transporting, moving, conveying, sorting, and storing goods and materials. One type of collapsible box can be quickly and easily collapsed for compact storage and quickly and easily set up for use.

There have been various attempts to provide improved collapsible boxes. However, the conventional collapsible boxes are often difficult to collapse, and even more difficult to change from a collapsed position to a non-collapsed position. Moreover, many types of conventional collapsible boxes often include removable parts that can be easily lost.

There have been numerous suggestions in prior patents for collapsible box. For example, U.S. Pat. No. 4,693,387 discloses a foldable box for receiving hanging files. It has resilient rails which are removably inserted by flexing the rails and inserting their ends into sockets formed in the sides of the box. The file box has a bottom panel, a top channel frame, and inwardly collapsible side panels. An end panel at each end of the box is hinged to an end piece of the top frame. When they swing down to a vertical position, the end panels lock the collapsible side panels to erect the box. For receiving and maintaining a pair of file rails in a spaced parallel relationship, aligned sockets are provided at the ends of the rails so that the file rails may be inserted therein by flexing.

U.S. Pat. No. 7,229,001 discloses a folding collapsible rectangular storage box wherein the box body has a flexible bottom panel, two short upright peripheral panels and two long upright peripheral panels perpendicularly extending upward from the four sides of the bottom panel, the two long upright peripheral panels having a respective vertically extending fold line arranged diagonally so that the box body can be folded into a flat one by pushing the long upright peripheral panels toward each other and then respectively turning the short upright peripheral panels toward the attached long upright peripheral panels.

U.S. Pat. No. 7,431,172 discloses a collapsible for providing access through both its top and front side. When set up, the box comprises a horizontal upper section and horizontal lower section, the sections attached to each other via a pair of opposed vertical sidewalls. When the upper section is gripped by hand and lifted upwardly, the upper section will separate from the lower section and the box will open. Each sidewall comprises a set of upper and lower panels, the panels attached to each other via a hinge that extends horizontally across the approximate center of the sidewall. The top of each sidewall is attached to one end of the upper section via a horizontal hinge. The bottom of each sidewall is attached to one end of the lower section via a horizontal hinge. The lower section comprises the floor of the box. The upper section comprises the top lid and two panels that rest horizontally underneath the top lid.

Thus, continuing improvements in the exploitation of collapsible box are constantly being sought.

Alternatively, the aesthetic, soft member for enclosing the receptacle 2 may be made of flexible plastic, leather or the like in other embodiments. The bottom 9 of the receptacle 2 comprises an opening 90 extending straight ahead from a bottom point of the fold line 7 to a bottom point of two joining side panels 8.

The collapsible box 1 further comprises a separate bottom panel 3 adapted to fit on the bottom 9 of the set up receptacle 2 for increasing a structural strength of the receptacle 2 if the receptacle 2 is expected to have a heavy load.

The collapsible box 1 further comprises a separate cover 5 being enclosed by an aesthetic, soft member (e.g., clothe made of fabric) (not shown). The cover 5 comprises a hard top 51, a soft interconnection (not numbered) extending from a peripheral edge of the top 51 and comprising five interconnected rectangular sections 50, and five distinct, inner, rectangular, hard, flange panels 4 having two short side edges 43, 44, an elongated top edge 42, and an elongated bottom edge 41 hingedly secured to a bottom edge 501 of each section 50 by means of stitching. Alternatively, the aesthetic, soft member for enclosing the cover 5 may be made of flexible plastic, leather or the like in other embodiments.

For folding the set up cover 5 (see FIG. 3), a person may first pivot the upright flange panels 4 about the bottom edges 41 thereof about at least 45 degrees. As a result, the sections 50 of the interconnection collapsed to rest upon a bottom of the top 51. Next, press the flange panels 4 one by one and lay one end of one flange panel 4 over the other end of an adjacent flange panel 4 until they are rested upon the folded sections 50 of the interconnection. As an end, the cover 5 is collapsed (see FIG. 4).

All of the side panels 8, the bottom panel 3, the flange panels 4, and the hard top 51 of the cover 5 are made of a hard sheet material such as hard plastic, wood, or other suitable materials. The first and second segments 81, 82 are joined together by means of stitching.

A zipper, at least one button and buttonhole combination, or a hook and loop fabric fastener (all not shown) may be provided on the opening 90 so as to enable an opening or closing of the bottom 9 of the receptacle 2.
